Economic Impact of DST in United States
The economic effects of Daylight Saving Time in United States are real but modest, and studies disagree on their size. Retailers and hospitality businesses generally favour DST, arguing that lighter evenings encourage shopping, dining out and other after-work spending — the US retail lobby was one of the main forces behind the 2005 extension of the DST period.
The transitions themselves carry a cost. Research from Chmura Economics has put the one-off economic cost of the spring change in the United States at roughly $430 million a year, driven by lost productivity, workplace injuries and the health effects of a disrupted night's sleep.
Agricultural Considerations
The story that DST was introduced for farmers has it exactly backwards. Farmers in United States and elsewhere were among its most persistent opponents, and the American farm lobby successfully campaigned to have national DST repealed after the First World War.
The reason is straightforward: farm work follows the sun, not the clock. Moving the clock forward just means doing the same work an hour earlier by the clock, while deliveries, markets and hired labour all shift with it. Dairy farmers make the point most often, since cows keep to their own schedule and take several days to adjust to a changed milking time.
Getting ready
- Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
- Set your clocks before going to bed to avoid confusion in the morning.
- Consider the time change when scheduling meetings with people in other time zones.
- Check and replace smoke detector batteries when changing clocks - it's a good reminder!
Frequently asked questions
When do the clocks change in United States in 2027?
Clocks go forward on Sunday, March 14, 2027 and back on Sunday, November 7, 2027.
Which way do the clocks go?
"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.
Do I have to change anything myself?
Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.
Is Daylight Saving Time being scrapped?
It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
